Description
BACKGROUND
Technical Field
[0001] The invention relates to a composite material structure, in
particular to a composite material structure that may improve air
permeability, elastic uniformity, and design flexibility of
clothing.
Description of Related Art
[0002] Generally speaking, a laminating structure may be used in
clothing to make the appearance more aesthetic and provide a
shaping function (adjust the body shape by laminating a
double-layer structure in a specific area). In the prior art, as
shown in FIG. 1, the laminating structure mostly adopts a
thermoplastic film, and a layer of thermoplastic film 12 is
sandwiched between two cloth layers 10. This existing structure has
the shortcomings of lack of breathability and poor comfort and
ductility, especially when used in sportswear or fitting clothing,
and the elasticity may be affected by a high-temperature hot-press
process. When the temperature is raised, the elasticity may be
decreased, and the issue of uneven elasticity may also occur.
[0003] Based on the above, the development of a composite material
structure suitable for clothing to alleviate the shortcomings of
lack of breathability, poor comfort, and decreased and uneven
elasticity of the existing laminating structure is an important
subject for current research.
SUMMARY
[0004] The invention provides a composite material structure that
may improve the breathability and comfort of clothing, the
uniformity of elasticity, and the flexibility of design, and the
composite material structure is especially suitable for sportswear
or personal clothing.
[0005] A composite material structure of the invention includes a
first cloth layer, a second cloth layer, a breathable thermoplastic
material layer, and a lining cloth layer. The breathable
thermoplastic material layer is located between the first cloth
layer and the second cloth layer and disposed on the first cloth
layer. The lining cloth layer is located between the first cloth
layer and the second cloth layer, and is formed by a base cloth and
a dispensing layer, and the base cloth is disposed on the second
cloth layer via the dispensing layer.
[0006] In an embodiment of the invention, the breathable
thermoplastic material layer includes a dispensing structure or a
mesh made of a thermoplastic material.
[0007] In an embodiment of the invention, a material of the base
cloth includes a copolymer or a blend of thermoplastic polyurethane
(TPU), polyethersulfone (PES), polyamide (PA), thermoplastic
polyurethane elastomer (TPU), thermoplastic polyester elastomer
(TPEE), or a combination thereof.
[0008] In an embodiment of the invention, the dispensing layer is
made by a dispensing process, including coating a polymer resin
colloid on the second cloth layer.
[0009] In an embodiment of the invention, the dispensing structure
is made by a dispensing process, including coating a polymer resin
colloid on the first cloth layer.
[0010] In an embodiment of the invention, the polymer resin colloid
includes a copolymer or a blend of polyethersulfone (PES),
polyamide (PA), thermoplastic polyurethane elastomer (TPU),
polyethylene (PE), polymethyl methacrylate (PMMA), or a combination
thereof.
[0011] In an embodiment of the invention, the thermoplastic
material includes a copolymer or a blend of polyethersulfone (PES),
polyamide (PA), thermoplastic polyurethane elastomer (TPU),
polyethylene (PE), polymethyl methacrylate (PMMA), or a combination
thereof.
[0012] Based on the above, the composite material structure of the
invention includes a lining cloth layer composed of a base cloth
and a dispensing layer, and a breathable thermoplastic material
layer. The gaps in the dispensing layer and the breathable
thermoplastic material layer may provide good breathability and
improve comfort. Moreover, the elasticity of the composite
structure of the invention may be adjusted via the selection of the
base cloth in the lining cloth layer. Compared with the
thermoplastic film used in the existing structure, the lining cloth
layer used in the composite material structure of the invention
does not melt during a high-temperature fusion process. In this
way, the composite material structure of the invention is
relatively insensitive to heat, and therefore elasticity is not
affected by a high-temperature process, and therefore, uniform
elasticity may be provided in the process. Moreover, in the
invention, different composite material elasticities may be created
by using interlining cloths having different elasticities, and
therefore more flexibility in design may be achieved.
[0013] In order to make the above features and advantages of the
invention better understood, embodiments are specifically provided
below with reference to figures for detailed description as
follows.

[0014] FIG. 1 is a diagram of an existing laminating structure.
[0015] FIG. 2 is a diagram of a composite material structure
according to an embodiment of the invention.

DESCRIPTION OF THE EMBODIMENTS
[0024] In the present specification, for clarity, the size and
proportion of layers and areas in the figures may be exaggerated.
In addition, the number of dispensing in the dispensing layer or
the dispensing structure shown is only for illustrative purposes,
and the invention is not limited thereto, and adjustments may be
made according to actual operating conditions.
[0025] FIG. 2 is a diagram of a composite material structure
according to an embodiment of the invention.
[0026] Please refer to FIG. 2, the composite material structure
includes a first cloth layer 20a, a second cloth layer 20b, a
breathable thermoplastic material layer 28, and a lining cloth
layer 26. In more detail, the breathable thermoplastic material
layer 28 and the lining cloth layer 26 are both located between the
first cloth layer 20a and the second cloth layer 20b. The
breathable thermoplastic material layer 28 is disposed on the first
cloth layer 20a to improve wearing comfort and breathability. The
lining cloth layer 26 is composed of a base cloth 24 and a
dispensing layer 22. The base cloth 24 is disposed on the second
cloth layer 20b via the dispensing layer 22. Therefore, not only
may the dispensing layer 22 improve the wearing comfort and
breathability, compared to the thermoplastic film used in the
existing structure, the base cloth 24 of the lining cloth layer 26
is less sensitive to heat, and therefore elasticity is not affected
by a high-temperature process.
[0027] In the present embodiment, the breathable thermoplastic
material layer 28 may include a dispensing structure (as shown in
FIG. 2) or a mesh made of a thermoplastic material, wherein the
thermoplastic material may include a copolymer or a blend of
polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane
elastomer (TPU), polyethylene (PE), polymethyl methacrylate (PMMA),
or a combination thereof, but the invention is not limited thereto.
That is, even though the breathable thermoplastic material layer 28
shown in FIG. 2 has a dispensing structure, other breathable
thermoplastic materials or processes may also be used as
appropriate. The material of the base cloth 24 may include a
copolymer or a blend of thermoplastic polyurethane (TPU),
polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane
elastomer (TPU), thermoplastic polyester elastomer (TPEE), or a
combination thereof. However, the invention is not limited thereto.
Other elastic cloths may be used as appropriate to control the
elasticity of the composite structure of the invention, and base
cloths 24 having different elasticities, stretch recovery rates,
and size specifications may also be used to improve design
flexibility.
[0028] In the present embodiment, the dispensing layer 22 and the
breathable thermoplastic material layer 28 adopting a dispensing
structure may be made by a dispensing process. For example, a
polymer resin colloid may be coated on the first cloth layer 20a to
form the breathable thermoplastic material layer 28 adopting a
dispensing structure; a polymer resin colloid may be coated on the
second cloth layer 20b to make the dispensing layer 22. The polymer
resin colloid may include a copolymer or a blend of
polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane
elastomer (TPU), polyethylene (PE), polymethyl methacrylate (PMMA),
or a combination thereof. However, the invention is not limited
thereto.
[0029] Based on the above, the composite material structure of the
invention includes a lining cloth layer composed of a base cloth
and a dispensing layer and a breathable thermoplastic material
layer, and is particularly suitable for sportswear or personal
clothing. Compared with the existing laminating structure using
thermoplastic film, in the invention, the air permeability,
comfort, and ductility of clothing may be improved via the gaps in
the dispensing layer and the breathable thermoplastic material
layer, and elasticity is not affected by a high-temperature
process, and therefore elastic uniformity may be further improved.
Moreover, in the invention, the elasticity of the composite
structure of the invention may be adjusted via the selection of the
base cloth in the lining cloth layer, and different composite
material elasticities may also be created by using lining cloths
having different elasticities. Therefore, more flexibility may be
achieved in design.
[0030] Although the invention is disclosed as above by the
embodiments, the embodiments are not intended to limit the
invention. Any person skilled in the art may make some changes and
modifications without departing from the spirit and scope of the
invention. Therefore, the scope of the invention shall be subject
to what is defined in the claims.
